Luka Modric is back in form and the Real Madrid midfielder will have a key part to play when his side faces off against Barcelona in the semifinals of the Copa del Rey on Wednesday.

A last-four tie that pits Spain's biggest two clubs together is a mouth-watering prospect, with the recent resurgence of both Modric and Madrid threatening Barca's recent dominance of the cup, FourFourTwo reported.

Barca is hunting a fifth consecutive Copa del Rey crown and with Madrid well off the pace in La Liga – the European Champions are eight points behind the league leaders – this could be its best chance of adding to the silverware it won at last year's Club World Cup.

Santiago Solari has finally found a winning formula at the Santiago Bernabeu, with Madrid victorious in five games in a row in all competitions ahead of Wednesday's first-leg trip to Camp Nou.

Central to its success has been Modric, who is hitting top form again after a slow start to the season that was disrupted by speculation he could leave for Serie A giants Inter, as well as understandable fatigue from his efforts in leading Croatia to the World Cup final.

Modric was rightly garlanded as the player of the tournament at the end of Russia 2018 but when he collected a maiden Ballon d'Or in December's glitzy ceremony, it felt slightly jarring.

The 33-year-old had been struggling under Julen Lopetegui with his below-par performances contributing to the bad results that led to the sacking of the former Spain coach.

Solari's arrival

Modric did not seem to significantly improve when Solari came in to replace Lopetegui, although Madrid won all four games of his interim spell in charge.

A 3-0 loss at Eibar after the caretaker was handed a permanent contract brought Madrid back down to earth with a bump and the home defeat to CSKA Moscow by the same scoreline in the Champions League showed Solari did not have a magic wand.

But, since the turn of the year, Modric appears to have rediscovered his form, with goals in consecutive La Liga wins against high-flying neighbor Sevilla and Real Betis helping to clinch vital points for Madrid in January.

Perhaps Modric is taking his own advice. After scoring the opening goal in Madrid's victory over Al Ain in the Club World Cup final, he vowed, "I should shoot more, it's true."

Back in goals

With three goals in his past eight appearances for Madrid, Modric is certainly undergoing something of a goalscoring renaissance.

And Los Blancos have needed his goals with both Marco Asensio and Gareth Bale having been sidelined by injury of late, coupled with the sale of Cristiano Ronaldo to Juventus leaving the club shorn of their most regular scorer.

Modric used to be surprisingly prolific. At the start of his career he hit 27 goals in three seasons for Dinamo Zagreb, his performances as a number 10 earning him a move to Tottenham.

It was there that Harry Redknapp – who was credited in Modric's Ballon d'Or acceptance speech – opted to move the Croatian into a deeper midfield role so he could dictate the tempo of Spurs' play.

Modric has only once scored more than three league goals in a season since leaving Zagreb but, as he approaches the end of his career, he appears to be shooting more often again.

Barcelona would not have expected Modric to be a major goal threat, but Ernesto Valverde must have a plan of action to combat the Madrid midfielder's rockets from range on Wednesday.

Modric has never scored in the Copa del Rey before and there may never be a better time to break his duck in the competition.
